of the fan conductor.

If you use water in cleaning the unit or its parts, do not let it flow to the

electrical parts.

4.4. Condensing water

During the heating season, humidity of extract air condenses to water.

Water formation may be abundant in new buildings or if ventilation is

low compared to the humidity build-up caused by the residents. Condensing

water needs to flow out from the ventilation unit without hindrance. In

connection with maintenance, e.g. in autumn before the beginning of the

heating season, make sure that the condensing water outlet (L) in the

bottom tank is not clogged. You may check it by pouring a little water in

the tank. Clean if necessary. Do not let water flow to the electrical parts.
